Offer remote assistance error on XP Pro

[HelloMan]

Hi,
Here is the scenario:
Expert and beginner machines are in the same domain, same LAN
Expert user account is in the administrator group of the beginner machine.
Beginner machine has all firewall turned off.
Both machines are running XP Pro
The remote assistance option is turned on in both machines.
Group policy is enabled for Remote assistance on both machines.
DCOM is enabled on both machines.
The Expert can access the share resources from the Beginner machine and vice
versa.

In the Expert machine, I tried to offer remote assistance to beginner
machine (without the beginner send out the invitation), I typed in the
machine IP, and then I choose the user to help and click start . The remote
assistance is trying to connect to the beginner machine. However, I got the
following error message:

A Remote Assistance connection could not be established. You want to check
for network issues or determine if the invitation expired or was cancelled
by the person who sent it.

Does any one has any clue?
I have changed the Remote Desktop port to something else, will this be the
issue?

thanks.

The Remote Assistance "Offer" functionality only works in a domain or
trusted domain environment. Is that your case?

If so see these links for help...
